Isalo National Park
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between . History and significance Isalo National Park was created in 1962 and has been administered by the Madagascar National Parks authority since 1997. The Bara people have traditionally inhabited this area, a nomadic people subsisting on cattle (zebu) farming. There are burial sites of the Bara people and some older burial sites of the Sakalava. Isalo is primarily within the Madagascar dry deciduous forests, dry deciduous forests ecoregion, an ecoregion in which natural vegetation has been reduced by almost 40% of its origin ...

Erik Acharius
Erik Acharius (10 October 1757 – 14 August 1819) was a Swedish botanist who pioneered the Taxonomy (biology), taxonomy of lichens and is known as the "father of lichenology". Acharius was famously the last pupil of Carl Linnaeus. Life Acharius was born in 1757 to Johan Eric Acharius and Catharina Margaretha Hagtorn in Gävle.Sernander., K. “Erik Acharius - Svenskt Biografiskt Lexikon.” Fredrik Teodor Borg - Svenskt Biografiskt Lexikon, sok.riksarkivet.se/sbl/Presentation.aspx?id=5503. He received a private education until he was admitted to Gävle Gymnasium in 1770. Later he matriculated at Uppsala University in 1773 where he studied natural history and medicine under Linnaeus and was the last student to defend a dissertation before him.Thell, A., Kärnefelt, I., Seaward, M., & Westberg, M.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context.

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliciaceae
The Caliciaceae are a family (taxonomy), family of mostly lichen-forming fungus, fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (mycology), division Ascomycota. Although the family has had its classification changed several times throughout its taxonomy (biology), taxonomic history, the use of modern molecular phylogenetic methods has helped to establish its current placement in the order Caliciales. Caliciaceae contains 39 genera and about 670 species. The largest genus is ''Buellia'', with around List of Buellia species, 300 species; there are more than a dozen genera that monotypic taxon, contain only a single species. Most Caliciaceae grow on corticolous lichen, bark, lignicolous lichen, dead wood, or saxicolous lichen, rocks. Some members of this family, particularly those of the type genus, ''Calicium'', are characterized by the presence of thin-walled and short-lasting ascus, asci (spore-bearing cells) and a mazaedium, which is an accumulat ...

Caliciales
Caliciales is an order of mostly lichenized fungi in the class Lecanoromycetes. It consists of two families: Caliciaceae and Physciaceae, which together contain 54 genera and more than 1200 species. The order was circumscribed by American botanist Charles Edwin Bessey in 1907. Families and genera , Species Fungorum (in the Catalogue of Life) accepts 2 families, 56 genera, and 910 species in the Caliciales. *Caliciaceae ::'' Acolium'' – 5 spp. ::'' Acroscyphus'' – 1 sp. ::'' Allocalicium'' – 1 sp. ::''Amandinea'' – 83 spp. ::'' Australiaena'' – 1 sp. ::'' Baculifera'' – 18 spp. ::''Buellia'' – 201 spp. ::''Calicium'' – 36 spp. ::'' Chrismofulvea'' – 3 spp. ::'' Ciposia'' – 1 sp. ::'' Cratiria'' – 23 spp. ::'' Dermatiscum'' – 2 sp. ::'' Dermiscellum'' – 1 sp. ::'' Dimelaena'' – 10 spp. ::'' Diploicia'' – 6 spp. ::'' Diplotomma'' – 12 spp. ::''Dirinaria'' – 18 spp. ::'' Endohyalina'' – 10 sp. ::'' Fluctua'' – 1 sp. ::'' ...

Taxa Named By William Nylander (botanist)
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
